Battery Information Video
New to airsoft? Here are some safety tips for airsoft guns that we recommend following.

Description:
Upgrade your AEG's fps to 380 to 410fps. It is highly recommended to upgrade plastic bushings and spring guide to metal bushings and spring guide with this product. Also, it would be wise to upgrade plastic pistons to polycarbonate piston; plastic piston heads to duracon piston heads; and standard gears to reinforced steel gears. Finally for best results a battery upgrade is also recommended.

Definately is more tense than a stock Echo 1 spring and adds some good fps. Fits fine with my Echo 1 cylinder set and Echo 1 spring guide.
